I’ve recently tried mixing the used coffee grounds in baking soda, and I’m seeing a very visible chemical reaction. I haven’t tried putting it in the ground yet though.

    Sorry I’ve been asleep at the wheel for this community.

    Anyway, there is a lot of good info here in the advice you already got.

    Coffee grounds aren’t acidic, and their pHs are typically 6-7 which is fine. pH usually doesn’t start becoming an issue until it approaches 5.

    Further, grounds have a great C:N ratio, which means they will decompose relatively fast in the soil, and won’t tie up N like other amendments do.
